UNITEU STATES JAMES BARKER, 0F KALAMAZOO, MICHIGAN.

TEMPORARY BINDER.

Application filed October 29,- 1920.

To all whom it may concern Be it known that I, JAMES BARKER, a citizen of the United States, residin at the city and county of Kalamazoo, gtate of Michigan, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to improvements in term orary binders.

y improved temporary binder relates particularly to the type of binder which has become known to the trade as tray binders, such binders being used particularly for machine accounting where it is desired to remove the sheets from the binder for making the records, the binder members being separated to facilitate the removing and replacing of the sheets.

It is the main object of this invention to provide an improved temporary binder provided with a removable locking post for the sheets in which the binder members cannot be secured together without the placing of the sheet locking post thereby insuring the securing of the sheets.

A further object is to provide a structure having these advantages which is comparatively simple, economical to produce and easy to manipulate.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is the preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a rear perspective view of a binder embodying the features of my invention.

Fig. II is a longitudinal section through the binder members on a line corresponding to line 22 of Figs. III, IV and V, parts being shown in full lines for convenience in illustration.

Fig. III is a detail section on a line corresponding to line 33 of Fig. V.

Fig. IV is a detail section on a line corresponding to line 4-4 of Figs. II and V.

ies ponding to line 55 of Figs. II, III and Fig. VI is a plan view of the locking bar or slide.

Fig. VII is a perspective view of one of the post socket members.

Fig. VIII is a detail section correspond ing to that of Fig. II showing a modified arrangement of locking post.

Fig. IX is a detail plan view of a sheet adapted for the binder illustrated.

F i X is a detail view showing the binder mem ers separated.

Fig. XI is a longitudinal section through the binding members on a line corresponding to line 11l1 of Fig. XII showing an other modification in which the movable post constitutes a locking member for the binder.

Fig. XII is a detail plan view of structure shown in Fig. XI.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 and 2 designate the binder members generally, and 3 the covers which are secured to the binder members by the hinges 4:. The binder members are provided with telescoping back flanges 5. The binder member 2 is chambered to house the mechanism of the binder. The binder member 1 is provided with relatively fixed posts 6 while the binder member 2 is provided with relatively fixed posts 7. These posts as illustrated are of the sectional type.

Each binder member is provided with openings adapted to receive the posts carried by the other binder member.

The locking bar or slide 8 is supported by plates 9 and screws 10, the screws being carried by the inner wall of the binder member 2 and arranged through'slots 11 in the looking bar to enga e the plates 9 as clearly shown in Fig. I The locking bar is provided with a finger piece 12 projecting through a hole 13 in the inner wall 14 of the binding member 2.

The coiled spring 15 is connected to the locking bar to urge it to locking position.

I also provide a removable sheet locking post 16, the sheet 17 (see FigpIX) being provided with notches 18 to receive the relatively'fixed posts, and a hole 19 to recelve the removable locking post 16 so that when sheets are assembled in the binder with the post 16 engaging the holes l9the sheets are securely retained, but upon removal of the post 16 they are all freed.

p The binder member 2 is provided with socket members 20 for the ends of the posts 6 and removable post 16. These socket members 20 are provided with vertical slots 21 and are cutaway at 22 at their upper ends to permit the reduced portions 23 of the keyhole slets2eto pass into the sockets so that the locking bar engages the groove-like recess '6' of, the posts 6 thereby lockingjthe parts together. The enlarged'portions of the openings 24 are of such size as to permit the in-sertionzand removal of the posts when these enlarged, portions are in alinement with the sockets. A similar keyhole slot or opening 24. is provided for the [removable post 16. However, in this embodiment of ,my invention the locking bar does not perform any locking function for the removable I In the socket 20' for the removable post 16 Iarrange a disk-like detent 25 which is engaged'by the. spring 26 disposed through the detent and through the openings 21 in the socket, the ends of the spring engaging the wall of the binder member urging the detent normally upward, and when the locking bar is in its disengaged position the de tent member passes into opening 24 thereof, thenebypreventing the locking movement of the locking bar: until the detent is disengaged, and this is automatically done by the closing of the binder. members with the lockpost in position. If an attempt be made to close the binder without the locking post in position, the locking bar cannot be actuated to engage the posts 6, and the operator is thereby made aware of the fact that he has omitted the locking post. The advantage 01": this is that operators in closing binders of this type frequently neglect to introduce the locking post when binder .is closed, and when they are picked up the sheets fall out;

Disks 25 are provided for the sockets 20. While thesedisks of the sockets 20 do serve as means forlockin'g the locking bar that is not their main function, as the detent 25 answers the purpose. These disks 25 are 7 provided as a means of ejecting the posts 6 from the sockets when the locking bar is disengaged.

Iii-Fig. VIII I show an adaptation in which locking post 27 is introduced from the outside of the binder member 1, said binder member having a recess 28 therein 27 ,there being a slot 30 in the bottom of the XII binder members 32 and 33' are similar 7 in structure to that of the second embodiment, none of the fixed posts 34:, however, performing any locking function. g

The locking bar 35 is provided with a locking slot 36 adapted to coarct with the recess 37 of the removable post 38. post is removable through the binder member 32 which is provided with a recess .39 for the head of the post. The lockrng bar 31 is provided with an actuating spring 10 while the removable post has a socket 20 and dethe binder until the post 38 has been in serted.

My improved temporary binder is comparatively simple, is quite economical in structure and very convenient to use.

I have illustrated an adaptation or embodiment of myinvention which I find very satisfactory. I have not attempted to'illustrate certain modifications and adaptations of my improvements to other binders which I contemplate, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt as may be desired.
